Settlement Date Calculator
US stocks settle one trading day after the trade — T+1 since 28 May 2024. Weekends and market holidays do not count, which is where the arithmetic goes wrong.
The market is closed on Sunday 13 September 2026
15 Sep 2026 No trade can be placed that day, so the first session is Monday 14 September 2026, and that settles Tuesday 15 September 2026.
The 2026 year-end deadline
A trade on Thursday 31 December 2026 is the last of the year, but it settles in 2027. If what matters to you is settlement landing inside 2026 — and for some purposes it is settlement that counts, not the trade — the deadline is Wednesday 30 December 2026, one session earlier than the calendar suggests.

What T+1 actually changed
Until 28 May 2024 US securities settled two business days after the trade. They now settle one. That halved the window, and it moved every deadline that hangs off settlement a day earlier — which is the part that catches people, because the trade date is what you see and the settlement date is what several rules actually care about.
What settles T+1: US stocks, ETFs, corporate and municipal bonds, and options exercises. Government securities and most options trades were already T+1. Mutual funds settle on their own schedule set by the fund, and are not covered here.
Why the next calendar day is usually the wrong answer
“One day” means one trading day. A Friday trade settles Monday. A trade the day before Thanksgiving settles the Friday after it. A trade before a Monday holiday settles Tuesday. The exchange is closed for ten days most years, plus every weekend, and the calculator above counts sessions rather than dates for exactly that reason.
The holidays are computed from the rules the NYSE observes, not from a hand-kept list: nine fixed or nth-weekday holidays plus Good Friday, with a Saturday holiday taken on the Friday before and a Sunday holiday on the Monday after. One exception matters: New Year's Day falling on a Saturday is not observed at all — the exchange trades on 31 December that year. Those rules are checked against this site's own record of actual closures, which runs back to 1885.
When settlement is the date that counts
- Dividends. To receive one you must be a holder of record on the record date, and under T+1 the ex-dividend date is the record date itself. Buying on the ex-date does not get you the dividend.
- Year-end. Some tax treatments follow the trade date and some follow settlement. The panel above gives both dates so you can use whichever your situation calls for — and this is a question for whoever does your taxes, not for a calculator.
- Cash accounts. Proceeds are not available to reinvest until settlement. Trading them before that is what produces a good-faith violation.
- Selling a loss and buying it back. The wash-sale rule runs on a 61-day window around the sale and does not care how fast settlement is — what it does and does not disallow is a separate matter from this page.
